PULLEY-LAGGER.

Application filed April 15, 1818.

To all whom it may concern:

Be it known that I, FRANK WV. BnAn'o, a citizen of the United States. and a resident of Fairfield, in the county of (lay and State of Nebraska, have iifvented certain new and useful Improvements in lulley-Laggers. of which the following is a specification.

This invention relates to pulley laggers, and the primary object of the invention is to provide a device whereby a pulley face may be lagged or covered with belting by one person.

An object of this invention is to provide a device for facilitating the lagging or covering ofpulley faces which includes a pair of levers having belt gripping membe s carried thereby and pulley face gripping members pivotally connected to their lower ends and to alssociatc means with the lovers and the pulley face gripping members for holding the levers in ad]usted position to hold a section of belting, taut about the face of a pulley lllltll tlll. belting: is riveted or otherwise suitably attached to the pulley face.

A still'further object of this invention is to provide a belt lagger includingpulley face gripping members each of which comprises a )air of jaws otlset laterally from the main ody thereof, one being adapted to engage the outer surface of a pulley rim and the other the inner surface of the rim, to provide adjustable means carried by the outer or face engaging arm for securely clamping the members u on a pulley rim and also to provide latera 1y extending ribs upon the pulley engaging surface of the arms which engage the inner surface of the pulley rim to cause them to bite into the rim and to adapt the members for attachment to pulle s of various diameters.

()t or objects of the invention will appear in the following detailed description, taken in connectionwith the accompanying drawings, forming a part of this specificatlon, and in which drawings:-

Figure 1 'isa side eletyatiOn of a pulley showing the Jagger applied thereto.

Fig. 2 is a fragmentary section through 'the rim of a pulley' showing the lagger applied thereto. I

Patented Nov. 5, 1918.

Serial No. 228,708.

Fig 4 is a top plan of one of the pulley gripping members. I

Fig. 5 is a fragmentary section on the line 5?) of Fi 3. Referring more particularly to the drawings. A designates an ordinary pulley and B the belting to be attached to the face of the pulley. The improved lagger is generically ind cated by the letter C and it comprises sections 1 and 2, one of which is placed upon each side of the pulley.

The sections 1 and 2 each comprise a main body 5 which has a pair of spaced ears 6 formed upon one end of the same to which ears a lever 7 is pivotally connected as shown at 8. The body 5 has upstanding lugs 9 formed thereon between and to which lugs a. pawl 10 is pivotally connected. The pawl 10 eo-acts with the ratchet teeth 11 formed upon the edge of the enlargement 12 of the lever 7 for holdin" the lever in adjusted pivotal position. 'Ihe body 5 is provided with a pair of laterally offset arms 14 and 15, the arm 15 bein ositioned below the arm LL and adapte fhr engagement with the inner surface of a pulley rim as shown in Fig. l of the drawin s. The arm 14 is adapted to be ositione outwardly of the face of the pol e and a set screw 16 is adjustably carried y the arm 14, for binding engagementagainst the face of the pulley to force the lateral toothed ribs 17 which are formed uporr the upper face of the arm 15 into biting engagement with the inner surface of the pullev rim. .By providing the lateral teeth orribs 17, the body 5 will be adapted for attachment to pulleysof various diameters.

The lever 7 has a clam confining bracket 18 formed thereon and be t clamping bars 19 and 20 extend from one of the sections to the other. Set screws 21am carried by the bracket 18 for forcin the bar 19 against the belting B which belting is positioned between the bars 19 and 20 and also for forcing the bar 20 against the lower end of the confining brackets 18. H ds 22 are formed upon the ends of the ha i 9 and 20 to pretill eireuinterentially spat-ed. The end of the belting I3 is then riveted or otherwise suitably attaehe l to the pulley fare at one of these sets of openings and the belting is passed between the bars It and 2t) and rlulnpetl therebetn'een by the adjustment of the set seren's 2]. 'lhe body members 5 have previously been attaehed to the pulley rim, and after the belt has been properly eonltt't'ttll between the bars 1!) and itl. the levers T are rocked upon their pivots to stretieh the belt and hold it taut in taeial abutment with portions ol the tat-e ol the pulley and when eaeh set of eireumterentially spaeed open ings is reat'hed. the belt is riveted to the fare of the pulley and the lagger is moved about the pulley rim for streti-hing the next portion of the belt. to properly eover the pulley t'aee,
